BOTTLE-BRUSHING MACHINE.

Specification of Letters Patent.

Patented Nov. 23, 11915.

Application filed January 2, 1915. Serial No. 84.

To all whom it may concern: 1

Be it known that I, Josnrrr W. DAWSON, a citizen of the United States of America, a resident of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Bottle-Brushing Ma chines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to a machine for brushing or scrubbing the outer faces of bottles or similar articles, the object being to produce a simple and very etlicient means for guiding, supporting and rotating the bottles while they are being acted upon by a brushing or scrubbing device. With th1s object in view the machine preferably comprises a brush, a series of rotatable rollers arranged below the brush and constituting a support for the bottles, and a traveling bottle feeder adapted to push the bottles along the upper faces of the rollers. The rollers are rotated to impart a rotary movement to the bottles, and to positively prevent the bottles from rolling or bouncing from one roller to another, I provide a series of fixed division members which separate the bottles and form guideways through which the rotating bottles are conducted during the brushing operation.

Prior to this invention bottle brushing machines have been provided with horizontal rollers which support and rotate the bottles, each bottle being engaged with two rollers which rotate in the same directions. The

rollers of these earlier machines are arranged adjacent to each other so that the traveling bottles lie close to each other, and owing to the movement and arrangement of the rollers each bottle tends to roll or climb over one of the rollers. It has been found in practice that the rotating bottles passing through these earlier machines are sometimes broken by accidentally bouncing or rolling over one of the rollers and passing to show the brushes and the means for rotatmg the rollers. Fig. 11 is a side elevation partly in section. H1 is a transverse section of the upper portion of the machine. Fig. IV is a detail view illustrating the means for driving the rollers. Fig. V is a detail view showing roller, a bottle supported thereby and a pair of division members forming a guideway for the bottle.

1 designates the main side frames of the machine, and 2 designates brushes rotatably mounted between said side frames, each brush being provided with journals which extend through the side frames 1. Sprocket wheels 3, secured to the brush journals are driven through the medium of sprocket chains 4. The brushes rotate in the direc tion indicated by arrows in Fig. 11.

The means for feeding the bottles comprises a pair of sprocket chains 5, located near the side frames 1, each of said sprocket chains being fitted to an idle wheel 6 and a drive wheel 7. The idle wheels are secured to a shaft 8 and the drive wheels 7 are secured to a power shaft 9 which extends across the machine shown in Fig. I.

10 designates feeder bars extending across the'machine and having their ends secured to the sprocket chains 5. v

The means for supporting the bottles comprises a series of rollers R arranged below the brushes 2 and provided with journals 11 and 12 (Fig. H) which are rotatably fitted to bearing members 13, the latter being secured to the side frames 1. The rollers are rotated by means of a drive chain 14: arranged'as shown in Figs. 1H and 1V and fitted to sprocket wheels 15 secured to the roller journals 11. The drive chain 14% passes between the sprocket wheels 15 and is arranged over someof said sprocket wheels and under the remaining sprocket wheels 15. A. power wheel 16, located at one side of the machine, is fitted to the drive chain 14 as seen in Figs. Ill and IV. Division members 17' in the form of angle bars are arranged above the rollers R and secured to the bearing members 13 which extend across the machine. These division members 17 are parallel with the rollers R, and they are arranged to form a series of guideways for the bottles 13 which rest upon the rollers.

When the machine is in service the brushes rotate continuously in the direction indicated by arrows in Fig. II, the sprocket chains 5 travel continuously in the direction indicated by the arrow at the left hand end of Fig. 11, and the rollers R are rotated continuously. The bottles are fed onto an intake chute or runway 20 and they drop by gravity onto the rollers R. The chute 20 is 7 preferably pivotally supported at 21 so that its lower end is free to rise when the feeder bars 10 pass under said lower end. The traveling feeder bars 10, carried by the sprocket chains 5, push the bottles along the upper faces of the rollers, in a direction parallel with the axis of the rollers, and the brushes moving in the direction indicated by arrows force the bottles into engagement with said feeder bars; The bottles are rotated through the medium of the rollers R other.

I claim p r 1. A bottle brushing machine comprising a brush, a series of rotatable rollers arranged below said brush and constituting a support for the bottles, means for rotating said rollers so as to rotate the bottles, a traveling bottle feeder arranged between said brush and rollers and adapted to push the bottles along the upper faces of the rollers, and division members forming guideways for the bottles resting upon sa1d-rollers, said division members being so arranged that each bottlejwill lie directly above the axis of one of' s aid rollers.

2. A bottle brushing machine comprising a brush, a series of rotatable rollers arranged below said brush and constituting a support for the bottles, means for rotating said rollers so as to rotate the'bottles, a

traveling bottle feeder arranged between said brush and rollers and adapted to push the bottles along the upper faces of the rollers, and division members forming guideways for the bottles resting upon said rollers, said divisionmembers being so arranged that each bottle is supported by and rotated by only one of the rollers.

3. A bottle brushing machine comprising a brush, a movable bottle support arranged below said brush, means for operating said bottle support to rotate the bottles, a bottle feeding device between said brush and movable bottle support, and stationary guide bars forming guideways for the rotating bottles resting upon said movable bottle sup port.

4. A bottle brushing machine comprising a brush, a series of rotatable supporting members arranged below said brush and constituting a support for the bottles, means 7 for rotating said supporting members so as to rotate the bottles, a bottle feeding device for feeding the bottles along said rotatable supporting members, and guide bars arranged in planes on opposite sides of the axis of said rotatable supporting members to form guideways for the bottles resting upon said rotatable supporting members.

5. A bottle brushing machine comprising a brush, a series of rotatable rollers arranged below said brush and constituting a support for the bottles, means for rotating said rollers so as to rotate the bottles, a trav eling bottle feeder arranged between said brush and rollers and adapted to push the bottles along the upper faces of the rollers, and division members forming guideways for the bottles resting upon said rollers, said division 'members being so arranged that each bottle will lie directly above the axis of one of said rollers.

(3. A bottle brushing machine comprising a brush, a rotatable roller arranged below said brush and constituting a bottle support, means for feeding the bottle along said roller, means for rotating said roller to rotate the bottle supported thereby, and a pair of guide members arranged in planes on opposite sides of the axis of said roller to retain the bottle in a plane directly above said roller.
